The Rolling-Block Method also referred to as: "rolling-2,015-block, square-root-weighted, epoch-adjusted block time method” (or just “adjusted-block-time method,” or “dual-epoch method”).

This new method improves upon the constant-block-time method early in the epoch by including block times from the previous 2,015 blocks, instead of just the blocks from the current epoch, which can skew forecasts early in the epoch for lack of data points.
